Abstract:	V letu 2013 smo v laboratoriju Fakultete za kmetijstvo in biosistemske vede na željo Selekcijsko-poskusnega centra Ptuj (Semenarna Ljubljana) izvedli poskus, v katerem smo ugotavljali, kako termoterapija (tretiranje z vročim zrakom) vpliva na kalitev semen navadnega fižola. Termoterapija je ena izmed možnosti zatiranja bolezni, ki se prenašajo s semenom. Poskus smo izvajali na štirih različnih sortah navadnega fižola ('Jeruzalemski', 'Jabelski pisanec', 'Zorin', 'Cipro'), katerih seme smo izpostavili različnim toplotnim tretiranjem. Po termoterapiji smo seme posejali v vlažen pesek in postavili v rastno komoro (25 °C , 24-urna osvetlitev) za 8 dni. Po tem času smo rastline razvrstili v 3 kategorije: mrtvo seme, nenormalne klice in normalne klice. Ugotovili smo, da se različne sorte fižola specifično odzivajo na posamezna toplotna tretiranja. Sorta je imela kot dejavnik statistično značilno večji vpliv kot pa samo obravnavanje, zato je smiselno proučiti vpliv različnih kombinacij termoterapije na kalitev v večjem obsegu ter tako poiskati optimalno tretiranje za določeno sorto. Ugotovili smo tudi, da je statistično značilno več mrtvih semen, če po tretiranju semen ne posadimo takoj, pač pa jih pred sajenjem še 50 dni skladiščimo v hladilniku.

Title:	Effect of thermotherapy on germination of the common bean (Phaseolus vulgaris L.) seeds
Abstract:	In 2013, an experiment was carried out on the request of Selekcijsko-poskusni center Ptuj (Semenarna Ljubljana) in the laboratory of the Faculty of Agriculture and Life Sciences, in which we wanted to find out how thermotherapy (hot air treatment) affects germination of the common bean seeds. Thermotherapy is one of the approaches which may exterminate seedborne diseases. The experiment involved four varieties of common beans ('Jeruzalemski', 'Jabelski pisanec', 'Zorin', 'Cipro'), of which seeds were exposed to various heat treatments. After the treatment seeds were planted in wet sand for 8 days (25°C, 24 hours a day light). After that time plants were sorted into three categories: dead seeds, abnormal seedlings and normal seedlings. We found that different varieties of the common bean exhibited specific responses to particular heat treatments. The study showed that variety had significantly bigger effect than treatment itself. The results suggest that it would be useful to further investigate the effects of various combinations of thermotherapy on germination of various varieties on a larger scale in order to find optimal treatments for specific common bean varieties. We also found that the number of dead seeds was significantly higher when seeds had been kept in the refrigerator for 50 days instead of planting them immediately after treatment.
